Radio Broadcasting• Presenters and performers would

assemble in a studio and make a live broadcast.

• Powerful transmitters sent out radio waves representing the sound.

• These radio signals could be picked up by anyone within range with the right receiving equipment.

• The same basic technology is still in operation today.

Internet Radio• In recent years, a new form of

Radio broadcast over the Internet has arisen.

• It has the advantage that you can pick up stations from anywhere in the world. (WBRU, BBC Radio)

• The expensive transmission equipment necessary to make normal radio broadcasts is not required, so virtually anyone can start an Internet radio station. (‘Scoopsville’)

Podcasting• Podcasting is a variation of Internet

radio started in 2004.• Instead of listening to a radio show

while sitting in front of your PC, you can download an audio file of the show, and listen to it later on your digital audio player. (On-demand)

• Although it takes its name from the iPod, any digital audio player can receive podcasts. (iTunes)

What We’re Doing

• Over the next few lessons we will learn how to create our own audio content.

• We will use a FREE program called Audacity to record and edit the content.

Audacity Basics

• Load “rough track.wav” into Audacity• There are a number of mistakes in the

recording.• Edit out all the mistakes• If you need help, read “Audacity

Basics.doc”

• Extension: If you have corrected all the errors, see if you can make the recording exactly 1 minute long.

Summary• New technology has changed the

way radio is created and listened to.

• You can listen to programs from anywhere in the world broadcast on the Internet.

• You don’t have to sit in front of a PC to listen to Internet radio: programs can be downloaded to an MP3 player and listened to later.
